TECHNICAL FIELD
[0001] The utility model relates to metal die stamping processing technical field especially is related to a combined metal die punch. BACKGROUND
[0002] In metal die stamping processing, punch is one of the key components, and its quality and performance directly affect the quality and production efficiency of the stamping part. The traditional metal die punch usually adopts integral design, and has the problems of inconvenient replacement and high maintenance cost. In recent years, although some detachable punch designs have appeared, most of them have defects such as complex assembly and unstable connection. Therefore, how to design a combined metal die punch with simple structure, convenient assembly and stable connection has become a problem to be solved at present. SUMMARY
[0003] In order to overcome the defects of the prior art, the utility model provides a combined metal die punch, which aims to realize the quick combination and disassembly of the shaft handle seat and the punch seat through the magnetic attraction connection mode, and improve the assembly efficiency and stability of the die punch.
[0004] The combined metal die punch of the utility model comprises a shaft handle seat and a punch seat.
[0005] Four strong magnetic blocks are equidistantly installed on the outer side of the shaft handle seat, and a film pad is attached to the bottom of the strong magnetic block, which is used to increase the tightness of the magnetic attraction connection and protect the top of the iron rod from being worn.
[0006] Four through holes are formed in the inside of the shaft handle seat for the iron rods on the punch seat to penetrate.
[0007] Four iron rods are equidistantly installed on the top of the punch seat and are magnetically attracted to the strong magnetic blocks on the shaft handle seat. Since the shaft handle seat and the punch seat mainly bear large extrusion force and only need to bear small pulling force, the magnetic attraction connection mode is sufficient to ensure stability.
[0008] A limiting column is installed at the center of the top of the punch seat, and a limiting hole is arranged at the bottom of the shaft handle seat. The top of the limiting column extends into the inside of the limiting hole, which is used to ensure the stability of the shaft handle seat and the punch seat when they are combined.
[0009] A punch body is installed at the bottom of the punch seat, which is used to perform stamping operation.
[0010] In summary, the present application has the following beneficial technical effects:
[0011] Simple structure: the utility model realizes the combination of the shaft handle seat and the punch seat through the magnetic attraction connection mode, without the need for complex mechanical structures or fasteners, which reduces the manufacturing cost and maintenance difficulty.
[0012] 1. Easy assembly: the magnetic attraction connection of the iron rod and the strong magnetic block enables the shaft handle seat and the punch seat to be quickly combined together, improving the assembly efficiency.
[0013] 2. Stable connection: the cooperation of the limiting column and the limiting hole and the increase of the film pad ensure the stability of the shaft handle seat and the punch seat when combined, improving the precision and reliability of the stamping operation.
[0014] 3. Easy to replace: when the punch body is worn or damaged, only the punch seat needs to be disassembled for replacement, without the need to replace the entire punch, reducing maintenance costs. BRIEF DESCRIPTION OF DRAWINGS

[0019] The following will be combined with the Figs. 1-3 , the application is further described in detail.
[0020] A combined metal mold punch includes a shaft handle seat 1 and a punch seat 2.
[0021] The shaft handle seat 1 is a support component of the entire punch, and four strong magnetic blocks 101 are installed equidistantly on the outer side for magnetic attraction connection with the iron rods on the punch seat. The bottom of the strong magnetic block 101 is pasted with a film pad 103 to increase the tightness of the magnetic attraction connection and protect the top of the iron rod. Four through holes 102 are provided in the interior of the shaft handle seat 1 for the iron rods on the punch seat to pass through. The bottom of the shaft handle seat 1 is provided with a limiting hole for cooperation with the limiting column on the punch seat.
[0022] The punch seat 2 is an execution component for stamping operation, and four iron rods 201 are installed equidistantly on the top for magnetic attraction connection with the strong magnetic blocks on the shaft handle seat. A limiting column 203 is installed at the center of the top of the punch seat 2 for cooperation with the limiting hole at the bottom of the shaft handle seat to ensure the stability of the combination. A punch body 202 is installed at the bottom of the punch seat 2 for performing the stamping operation.
[0023] Assembly process: align the iron bar 201 on the punch seat 2 with the through hole 102 on the shaft holder 1 and insert, while aligning the limiting column 203 with the limiting hole and inserting. Due to the magnetic attraction between the strong magnetic block 101 and the iron bar 201, the shaft holder 1 and the punch seat 2 can be quickly and stably combined together. The bottom of the film pad 103 is in contact with the top of the iron bar 201, which increases the tightness of the magnetic attraction connection and protects the top of the iron bar from wear.
[0024] The standard parts used in the utility model can be purchased from the market, and the special-shaped parts can be ordered according to the description and the drawings, the specific connection mode of each part adopts the conventional means such as bolts, rivets and welding in the prior art, the machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts the conventional connection mode in the prior art, which will not be described in detail here.
[0025] The implementation principle of the combined metal mold punch of the embodiment of the application is that: in the stamping process, the shaft holder 1 is fixed on the stamping machine through a connecting part such as a bolt, and the punch body 202 at the bottom of the punch seat 2 contacts and stamps the workpiece. Since the shaft holder 1 and the punch seat 2 are stably combined through magnetic attraction and limiting cooperation, the smooth operation of the stamping operation can be ensured. When it is necessary to replace the punch body 202 or perform maintenance, only the punch seat 2 needs to be disassembled.
[0026] The above describes an exemplary embodiment of a combined metal mold punch provided by the present disclosure with reference to a preferred embodiment, however, those skilled in the art can understand that various modifications and improvements can be made to the above specific embodiments without departing from the concept of the present disclosure, and various technical features and structures proposed by the present disclosure can be combined without exceeding the protection scope of the present disclosure, and the protection scope of the present disclosure is determined by the appended claims.
